It was a unique challenge embarking on a list that quantifies some of the most influential horror titles of the past fifteen years. So many of the films coming out are derivative of films like Black Christmas, Halloween, Alien, Night of the Living Dead or An American Werewolf in London. And many of those films were derivative of Psycho or Peeping Tom and so on and so forth. So, it is incredibly difficult to identify films that have inspired contemporary filmmakers and brought a new angle or idea to the table when the table is already quite full and most every angle has been played out. But, there are still filmmakers that have managed to bring a new spin to an old idea or revitalized a faltering sub-genre with a fresh perspective. We owe a debt of gratitude to those filmmakers and the films that have helped to influence the state of the modern horror film.
